RESUMO
OBJECTIVES: To explore which core domain is best associated with the American College of Rheumatology (ACR) 20% response in trials assessing the effect of targeted interventions in rheumatoid arthritis (RA). METHODS: A meta-epidemiological study was performed on randomised trials investigating biologics and targeted agents compared with placebo or conventional disease-modifying antirheumatic drugs in patients with RA. The main outcome measures were ORs for the ACR 20% response and at least one of the eight core domains according to the existing RA core outcome set (COS) analysed based on standardised mean differences. RESULTS: 115 trials involving 55 422 patients with RA were eligible. The OR for achieving ACR 20% response was 3.19 (95% CI 2.96 to 3.44) for the experimental interventions relative to the comparators. The median number of COS domains reported was 6; 18 trials reported only 1 domain, 17 all 8. Univariable meta-regression analyses indicated that each of the eight core domains was significantly associated with ACR 20% response, yet improvements in physical disability explain a successful ACR 20% response the most. Including only trials reporting on all eight core domains, univariable meta-regression analyses proved improvement in fatigue to explain a successful ACR 20% response the most. CONCLUSIONS: Within this dataset, it is evident that the conclusions concerning our primary objective were significantly influenced by both the amount and characteristics of missing data. Our data suggest that fatigue could be more important for the primary endpoint than previously assumed, but this is based on limited data.
RESUMO
OBJECTIVE: To compare the effect of an illness perception conversation (IPC), relative to a research participation conversation (RPC), on 2-week changes in knee pain in patients with knee osteoarthritis. METHOD: This was a randomised single-blind trial. Patients were randomised to two matched conversations. An IP conversation concerning the participant's knee pain-related illness perception (IP) or an RPC concerning the participant's motivation for participating in research. Both conversations were followed by an open-label intraarticular saline injection in the most symptomatic knee. The primary outcome was change in knee pain from baseline to 2 weeks follow-up on a 100 mm visual analogue scale (VAS). Key secondary outcomes included the Knee injury and Osteoarthritis Outcome Score (KOOS) subscales: Activities of daily living (ADL) and Quality of life (QoL). Main analyses were based on the intention-to-treat population using repeated measures mixed effects linear models. RESULTS: 103 patients were randomised to the IPC group (n = 52) and the RPC group (n = 51). VAS knee pain scores changed statistically significantly from baseline to end of treatment in both groups, -13.7 (standard error [SE]: 3.2) in the IPC group and -13.0 (SE: 3.1) in the RPC group with an adjusted between-group difference of -0.7 (95% CI: -8.3 to 6.9; P = 0.85). Likewise, no group differences were seen in KOOS ADL and KOOS QoL. CONCLUSION: A conversation concerning knee pain-related IP did not augment the pain-relieving effect of an open-label placebo injection when compared to a similar control conversation concerning motivations for participating in research. TRIAL REGISTRATION: NCT05225480.
RESUMO
OBJECTIVE: To examine the pain relief effects of comparators (placebos and untreated control groups) in hand osteoarthritis trials and the impact of contextual factors. METHODS: We systematically searched PubMed, EMBASE and CENTRAL from inception to December 26, 2021. We included randomised controlled trials of people with hand osteoarthritis with a placebo or an untreated control group. We assessed the Risk of Bias with Cochrane Risk-of-Bias tool version 2. Each comparator was contrasted with a null-arm, imputed as having a zero change from baseline with the same standard deviation as the comparator. We combined the standardised mean differences with a random effects meta-analysis. The contextual factors' effect was explored in meta-regression and stratified models with pain as the dependent variable. RESULTS: 84 trials (7262 participants) were eligible for quantitative synthesis, of which 76 (6462 participants) were eligible for the stratified analyses. Placebos were superior to their matched null-arms in relieving pain with an effect size of -0.51 (95% confidence interval -0.61 to -0.42), while untreated control groups were not. When analysing all comparators, blinded trial designs and low risk of bias were associated with higher pain relief compared to an open-label trial design and some concern or high risk of bias. CONCLUSION: The placebo response on pain for people with hand osteoarthritis was increased by appropriate blinding and a lower risk of bias assessment. Placebos were superior to a null-arm, while untreated control groups were not. Results emphasise the importance of using appropriate comparators in clinical trials.

OBJECTIVES: There is growing interest in collecting outcome information directly from patients in clinical trials. This study evaluates what patients with rheumatic and musculoskeletal diseases (RMDs) consider important to know about symptomatic side effects they may experience from a new prescription drug. METHODS: Patients with inflammatory arthritis, who had one or more prescribed drugs for their disease for at least 12 months, participated in focus groups and individual interviews. Discussions were analysed using reflexive thematic analysis. RESULTS: We conducted seven focus groups with 34 participants across three continents. We found four overarching and two underpinning themes. The 'impact on life' was connected to participants 'daily life', 'family life', 'work life', and 'social life'. In 'psychological and physical aspects' participants described 'limitation to physical function', 'emotional dysregulation' and 'an overall mental state'. Extra tests, hospital visits and payment for medication were considered a 'time, energy and financial burden' of side effects. Participants explained important measurement issues to be 'severity', 'frequency', and 'duration'. Underpinning these issues, participants evaluated the 'benefit-harm-balance' which includes 'the cumulative burden' of having several side effects and the persistence of side effects over time. CONCLUSIONS: In treatment for RMDs, there seems to be an urgent need for feasible measures of patient-reported bother (impact on life and cumulative burden) from side effects and the benefit-harm-balance. These findings contribute new evidence in support of a target domain-an outcome that represents the patient voice evaluating the symptomatic treatment-related side effects for people with RMDs enrolled in clinical trials.
RESUMO
The prevalence and disease burden of chronic inflammatory diseases (CIDs) are predicted to rise. Patients are commonly treated with biological agents, but the individual treatment responses vary, warranting further research into optimizing treatment strategies. This study aimed to compare the clinical treatment responses in patients with CIDs initiating biologic therapy based on smoking status, a notorious risk factor in CIDs. In this multicentre cohort study including 233 patients with a diagnosis of Crohn's disease, ulcerative colitis, rheumatoid arthritis, axial spondyloarthritis, psoriatic arthritis or psoriasis initiating biologic therapy, we compared treatment response rates after 14 to 16 weeks and secondary outcomes between smokers and non-smokers. We evaluated the contrast between groups using logistic regression models: (i) a "crude" model, only adjusted for the CID type, and (ii) an adjusted model (including sex and age). Among the 205 patients eligible for this study, 53 (26%) were smokers. The treatment response rate among smokers (n = 23 [43%]) was lower compared to the non-smoking CID population (n = 92 [61%]), corresponding to a "crude" OR of 0.51 (95% CI: [0.26;1.01]) while adjusting for sex and age resulted in consistent findings: 0.51 [0.26;1.02]. The contrast was apparently most prominent among the 38 RA patients, with significantly lower treatment response rates for smokers in both the "crude" and adjusted models (adjusted OR 0.13, [0.02;0.81]). Despite a significant risk of residual confounding, patients with CIDs (rheumatoid arthritis in particular) should be informed that smoking probably lowers the odds of responding sufficiently to biological therapy.

Unspecific symptoms of anxiety and distress are frequently encountered in patients in both general practice and acute psychiatric services. Minor tranquillizers may be a treatment option when non-pharmacological interventions are insufficient or unavailable. We conducted a systematic review with network meta-analysis of the evidence for short-term (1-4 weeks) pharmacological treatment of newly onset symptoms of anxiety and distress. We searched the PsycInfo, MEDLINE, EMBASE and Cochrane Library databases and extracted data following a predefined hierarchy of outcomes. We assessed risk of bias using the Cochrane Risk of Bias tool and the certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation framework (GRADE). We included 34 randomized trials comprising a total of 7044 patients with adjustment disorders or anxiety spectrum disorders. The network meta-analysis showed that regarding the critical outcome symptoms of anxiety within 1-4 weeks benzodiazepines (SMD - 0.58, 95% CI - 0.77 to - 0.40), quetiapine (SMD - 0.51, 95% CI - 0.90 to - 0.13) and pregabalin (SMD - 0.58, 95% CI - 0.87 to - 0.28) all performed better than placebo with no statistically significant difference between the drugs. Data on other important outcomes were inconsistently reported. Adverse effects varied, but overall, it was uncertain whether adverse effects differed between interventions. The evidence regarding the risk of dependence was uncertain, but dependence may be a concern in susceptible individuals even with short-term treatment. Overall, the certainty of the evidence according to GRADE was rated as low to very low across outcomes. Despite the limitations in the evidence, the results of this review can inform treatment guidelines, supporting clinicians in the choice of minor tranquillizer in this prevalent and help-seeking, clinically heterogeneous population.

INTRODUCTION: Data concerning the global burden of hidradenitis suppurativa (HS) are limited. Reported prevalence estimates vary between 0.0003% and 4.1%, and data from various geographical regions are still to be collected. Previously reported prevalences have been limited by the methodological approach and source of data. This has resulted in great heterogeneity as prevalence data from physician-diagnosed cases poorly match those of self-reported apparent HS disease. METHODS: The Global Hidradenitis Suppurativa Atlas (GHiSA) introduces an innovative approach to determine the global prevalence of HS. This approach involves using a previously validated questionnaire to screen apparently healthy adults accompanying a patient to a non-dermatological outpatient clinic visit in a hospital or a private/family medicine clinic. The screening questionnaire (i.e., the index test) is combined with a subsequent physician-based in-person validation (i.e., the reference standard) of the participants who screen positive. Approximately ten percent of the screen-negative participants are also clinically assessed to verify the diagnostic precision of the test. The local prevalence (pi) will be estimated from each country that submits the number of patients who are HS positive according to the index test and clinical examination (n), and the corresponding total number of observations (N). CONCLUSION: The GHiSA Global Prevalence studies are currently running simultaneously in 58 countries across six continents (Africa, Europe, Australia, North America, South America, and Asia). The goal of the combined global proportion is the generation of a single summary (i.e., proportional meta-analysis), which will be done after a logit transformation and synthesized using a random-effects model. The novel standardization of the Global Prevalence Studies conducted through GHiSA enables direct international comparisons, which were previously not possible due to substantial heterogeneity in past HS prevalence studies.

To evaluate tumour necrosis factor inhibitor (TNFi) drug-levels and presence of anti-drug antibodies (ADAb) in patients with inflammatory arthritis who taper TNFi compared to TNFi continuation. Patients with rheumatoid arthritis, psoriatic arthritis, or axial spondyloarthritis on stable TNFi dose and in low disease activity ≥ 12 months were randomised (2:1) to disease activity-guided tapering or control. Blood samples at baseline, 12- and 18-months were evaluated for TNFi drug-levels and ADAb. In total, 129 patients were randomised to tapering (n = 88) or control (n = 41). Between baseline and month 18, a significant shift in TNFi drug-levels were observed in the tapering group resulting in fewer patients with high drug-levels (change: - 14% [95% CI - 27 to - 1%]) and more with low drug-levels (change: 18% [95% CI 5-31%]). Disease activity was equivalent between groups at 18 months, mean difference: RA - 0.06 (95% CI - 0.44 to 0.33), PsA 0.03 (95% CI - 0.36 to 0.42), and axSpA 0.16 (- 0.17 to 0.49), equivalence margins ± 0.5 disease activity points. ADAb were detected in eight patients, all from the tapering group. TNFi drug-level category or ADAb were not predictive for achieving successful tapering at 18 months. TNFi drug-levels decreased during tapering which indicate adherence to the tapering algorithm. Despite the difference in TNFi drug-levels at 18 months, disease activity remained equivalent, and only few tapering patients had detectable ADAb. These data do not support using TNFi drug-level and/or ADAb to guide the tapering decision but future research with larger trials is needed.Trial registration: EudraCT: 2017-001970-41, December 21, 2017.
RESUMO
BACKGROUND: Weight gain and hypertension are well known adverse effects of treatment with high-dose glucocorticoids. OBJECTIVE: To evaluate the effects of 2 years of low-dose glucocorticoid treatment in rheumatoid arthritis (RA). DESIGN: Pooled analysis of 5 randomized controlled trials with 2-year interventions allowing concomitant treatment with disease-modifying antirheumatic drugs. SETTING: 12 countries in Europe. PATIENTS: Early and established RA. INTERVENTION: Glucocorticoids at 7.5 mg or less prednisone equivalent per day. MEASUREMENTS: Coprimary end points were differences in change from baseline in body weight and mean arterial pressure after 2 years in intention-to-treat analyses. Difference in the change of number of antihypertensive drugs after 2 years was a secondary end point. Subgroup and sensitivity analyses were done to assess the robustness of primary findings. RESULTS: A total of 1112 participants were included (mean age, 61.4 years [SD, 14.5]; 68% women). Both groups gained weight in 2 years, but glucocorticoids led, on average, to 1.1 kg (95% CI, 0.4 to 1.8 kg; P < 0.001) more weight gain than the control treatment. Mean arterial pressure increased by about 2 mm Hg in both groups, with a between-group difference of -0.4 mm Hg (CI, -3.0 to 2.2 mm Hg; P = 0.187). These results were consistent in sensitivity and subgroup analyses. Most patients did not change the number of antihypertensive drugs, and there was no evidence of differences between groups. LIMITATION: Body composition was not assessed, and generalizability to non-European regions may be limited. CONCLUSION: This study provides robust evidence that low-dose glucocorticoids, received over 2 years for the treatment of RA, increase weight by about 1 kg but do not increase blood pressure. PRIMARY FUNDING SOURCE: None.

BACKGROUND: Current recommendations regarding the use of surgical left atrial appendage (LAA) closure to prevent thromboembolisms lack high-level evidence. Patients undergoing open-heart surgery often have several cardiovascular risk factors and a high occurrence of postoperative atrial fibrillation (AF)-with a high recurrence rate-and are thus at a high risk of stroke. Therefore, we hypothesized that concomitant LAA closure during open-heart surgery will reduce mid-term risk of stroke independently of preoperative AF status and CHA2DS2-VASc score. METHODS: This protocol describes a randomized multicenter trial. Consecutive participants ≥18 years scheduled for first-time planned open-heart surgery from cardiac surgery centers in Denmark, Spain, and Sweden are included. Both patients with a previous diagnosis of paroxysmal or chronic AF, as well as those without AF, are eligible to participate, irrespective of their CHA2DS2-VASc score. Patients already planned for ablation or LAA closure during surgery, with current endocarditis, or where follow-up is not possible are considered noneligible. Patients are stratified by site, surgery type, and preoperative or planned oral anticoagulation treatment. Subsequently, patients are randomized 1:1 to either concomitant LAA closure or standard care (ie, open LAA). The primary outcome is stroke, including transient ischemic attack, as assigned by 2 independent neurologists blinded to the treatment allocation. To recognize a 60% relative risk reduction of the primary outcome with LAA closure, 1,500 patients are randomized and followed for 2 years (significance level of 0.05 and power of 90%). CONCLUSIONS: The LAACS-2 trial is likely to impact the LAA closure approach in most patients undergoing open-heart surgery. TRIAL REGISTRATION: NCT03724318.

OBJECTIVES: To compare tolerability and effectiveness of two different classes of biological Disease-Modifying Anti-Rheumatic Drugs (bDMARDs; interleukin (IL)-17- and IL-23(p19) inhibitors) relative to tumour necrosis factor inhibitors (TNFi) regarding the drug survival rates and treatment outcomes in patients with psoriatic arthritis (PsA). METHODS: We emulated a target trial on comparative effectiveness using observational data from a prospective cohort study based on the Parker Institute's PsA cohort - the PIPA cohort. All patients underwent interview and clinical examination programme at baseline and at follow-up visits at four and twelve months. The primary endpoint, drug survival, was assessed up to 12 months from baseline. We estimated hazard ratios from proportional hazards model and used propensity score adjustment in an attempt to deconfound and emulate a random treatment assignment. RESULTS: We included a total of 109 patients in the intention-to-monitor population at baseline initiating either TNFi (75 patients), IL17i (26 patients), or IL23(19)i (8 patients). Hazard ratios in the propensity adjusted model comparing IL-17i and IL-23(p19)i to TNFi were 1.36 (95% CI 0.59-3.14) and 0.56 (95% CI 0.10-3.24), respectively. TNFi and IL-17i had comparable effects regarding response rates and changes in clinical outcomes after 12 months, whereas IL-23(p19)i tended to perform better overall. CONCLUSION: No decisive differences between drugs were observed at group level regarding drug survival and clinical outcomes after 12 months. TNFi, IL-17i, and IL-23(p19)i may all be considered equally effective in the treatment of patients with PsA, advocating for investigating more in personalised treatment strategies.
RESUMO
OBJECTIVES: The primary objective was to compare the effect of cognitive behavioural therapy for insomnia (CBT-I) to usual care on sleep efficiency, measured by polysomnography (PSG) immediately after the intervention at week 7. Secondary objectives included comparing the longer-term effect on sleep- and RA-related outcomes at week 26. METHODS: In a randomized controlled trial using a parallel group design, the experimental intervention was 6 weeks' nurse-led group-based CBT-I; the comparator was usual care. Analyses were based on the intention-to-treat (ITT) principle; missing data were statistically modelled using repeated-measures linear mixed effects models adjusted for the level at baseline. RESULTS: The ITT population consisted of 62 patients (89% women), with an average age of 58 years and an average sleep efficiency of 83.1%. At primary end point, sleep efficiency was 88.7% in the CBT-I group, compared with 83.7% in the control group (difference: 5.03 [95% CI -0.37, 10.43]; P = 0.068) measured by PSG at week 7. Key secondary outcomes measured with PSG had not improved at week 26. However, for all the patient-reported key secondary sleep- and RA-related outcomes, there were statistically highly significant differences between CBT-I and usual care (P < 0.0001), e.g. insomnia (Insomnia Severity Index: -9.85 [95% CI -11.77, -7.92]) and the RA impact of disease (RAID: -1.36 [95% CI -1.92, -0.80]) at week 26. CONCLUSION: Nurse-led group-based CBT-I did not lead to an effect on sleep efficiency objectively measured with PSG. However, CBT-I showed improvement on all patient-reported key secondary sleep- and RA-related outcomes measured at week 26.

OBJECTIVES: The aim of this study was to assess the safety and efficacy of long-term low-dose glucocorticoids (GCs) in RA. METHODS: A protocolised systematic review and meta-analysis (PROSPERO No. CRD42021252528) of double-blind, placebo-controlled randomised trials (RCTs) comparing a low dose of GCs (≤ 7.5mg/day prednisone) to placebo over at least 2 years was performed. The primary outcome investigated was adverse events (AEs). We performed random-effects meta-analyses and used the Cochrane RoB tool and GRADE to assess risk of bias and quality of evidence (QoE). RESULTS: Six trials with 1078 participants were included. There was no evidence of an increased risk of AEs (incidence rate ratio 1.08; 95% CI 0.86, 1.34; P = 0.52); however, the QoE was low. The risks of death, serious AEs, withdrawals due to AEs, and AEs of special interest did not differ from placebo (very low to moderate QoE). Infections occurred more frequently with GCs (risk ratio 1.4; 1.19-1.65; moderate QoE). Concerning benefit, we found moderate to high quality evidence of improvement in disease activity (DAS28: -0.23; -0.43 to -0.03), function (HAQ -0.09; -0.18 to 0.00), and Larsen scores (-4.61; -7.52 to -1.69). In other efficacy outcomes, including Sharp van der Heijde scores, there was no evidence of benefits with GCs. CONCLUSION: There is very low to moderate QoE for no harm with long-term low dose GCs in RA, except for an increased risk of infections in GC users. The benefit-risk ratio might be reasonable forusing low-dose long-term GCs considering the moderate to high quality evidence for disease-modifying properties.

AIMS: To evaluate predictors for successful biologic tapering among patients with inflammatory arthritis using baseline characteristics from the BIODOPT trial. METHODS: Adult patients with rheumatoid arthritis, psoriatic arthritis or axial spondyloarthritis on stable biologic dose and in low disease activity ≥12 months were enrolled. Participants were randomized (2:1) to disease activity-guided biologic tapering or continuation of baseline biologic. Patients achieving successful tapering reduced their biologic dose by ≥50%, had no protocol deviations and were in low disease activity at 18 months. Modified Poisson regression with robust variance estimator was applied. RESULTS: In total, 142 patients were randomized to tapering (n = 95) or control (n = 47). Successful tapering was achieved by 32 and 2%, respectively. Tapering group was the only statistically significant independent predictor for successful tapering, risk ratio (RR): 14.0 (95% confidence interval [CI]: 1.9 to 101.3, P = .009). However, higher Short Form Health Survey 36 mental component summary (SF-36 MCS) was observed to be a predictor of potential importance, RR: 1.06 (95% CI: 0.99 to 1.13, P = .097). When limiting the analyses to the tapering group only, none of the baseline variables were statistically significant independent predictors but SF-36 MCS was still considered to be of potential importance, RR: 1.05 (95% CI: 0.99 to 1.12, P = .098). CONCLUSION: Successful tapering is a reachable target for 1 in 3 patients with inflammatory arthritis who are interested in reducing their biological therapy. No statistically significant predictors (besides allocation to tapering) were identified. Future research on mental health and tapering is encouraged.

OBJECTIVES: To compare plasma levels of 92 cardiovascular- and inflammation-related proteins (CIRPs) and to analyse for associations with anti-cyclic citrullinated peptide (anti-CCP) status and disease activity in early and treatment-naive rheumatoid arthritis (RA). METHODS: Olink CVD-III-panel was used to measure 92 CIRP plasma levels in 180 early, treatment-naive, and highly inflamed RA patients from the OPERA trial. CIRP plasma levels as well as correlation between CIRP plasma levels and RA disease activity were compared between anti-CCP groups. CIRP level-based hierarchical cluster analysis was performed in each anti-CCP group separately. RESULTS: The study included 117 anti-CCP-positive and 63 anti-CCP-negative RA patients. Among the 92 CIRPs measured, the levels of chitotriosidase-1 (CHIT1) and tyrosine-protein-phosphatase non-receptor-type substrate-1 (SHPS-1) were increased and those of metalloproteinase inhibitor-4 (TIMP-4) decreased in the anti-CCP-negative group compared to anti-CCP-positive group. The strongest associations with RA disease activity were found for interleukin-2 receptor-subunit-alpha (IL2-RA) and E-selectin levels in the anti-CCP-negative group and for C-C-motif chemokine-16 levels (CCL16) in the anti-CCP-positive group. None of the differences passed the Hochberg sequential multiplicity test, however, the CIPRs were interacting and thus the prerequisites of the Hochberg procedure were not fulfilled. CIRP level-based cluster analysis identified two patient clusters in both anti-CCP groups. Demographic and clinical characteristics were similar in the two clusters for each anti-CCP group. CONCLUSIONS: In active and early RA, the findings regarding CHIT1, SHPS-1 TIMP-4, IL2-RA, E-selectin, and CCL16 differed between the two anti-CCP groups. In addition, we identified two patient clusters that were independent of the anti-CCP status.

BACKGROUND: Primary axillary hyperhidrosis (PAH) affects 1-5% of the world's population who has an unmet need for improved treatments. The heating of sweat glands with specific microwave therapy has shown promising results, yet, treatment with widely available devices such as long-pulsed Neodymium Yttrium Aluminum Garnet (Nd:YAG) lasers, diode lasers or Intense Pulsed Light (IPL) may serve as pragmatic alternatives. OBJECTIVES: To compare sweat secretion of treated versus untreated contralateral control axilla 1-3 months after one session of Nd:YAG laser or IPL in patients with PAH. METHODS: A within-person randomized controlled trial. Patients were randomized to receive either one session of Nd:YAG laser or IPL in one axilla with the contra-lateral serving as control. Sweat production was assessed by gravimetry, trans-epidermal water loss, hyperhidrosis disease severity scale and dynamic optical coherence tomography. Mixed-effects models were used to handle the within-person design, containing both fixed effect factors (side, group, and subgroup), and random effects (patients), while also adjusting for the level at baseline. RESULTS: A total of 20 patients were enrolled. At follow-up 1-3 months after treatment, sweat secretion was not affected in the treated axilla when compared to the control axillae (0.01 [95%CI: -0.04 to 0.05]; p = 0.68). In the Nd:YAG subgroup (10 patients), least squares means for sweat secretion was 0.18 mg/5 min in the treated versus 0.15 mg/5 min in the control axilla, respectively, corresponding to a statistically insignificant mean difference of 0.02 mg/5 min (95% CI: -0.06 to 0.11; p = 0.54). In the IPL subgroup (10 patients), sweat secretion was 0.06 mg/5 min in the treated axilla versus 0.07 mg/5 min in the control axilla with a statistically insignificant difference of -0.01 points (95% CI: -0.03 to 0.02; p = 0.46). Likewise, none of the secondary outcomes were significantly affected by treatment. However, both treatments appeared safe and well tolerated with no adverse effects reported at follow-up. CONCLUSIONS: One treatment with external 1064 nm Nd:YAG laser or 640 nm IPL at commercially available settings, failed to demonstrate clinical benefit in treating PAH, with narrow confidence intervals implying that this was not due to a type-2 error.

BACKGROUND: Early diagnosis of cerebral palsy (CP) is important to enable intervention at a time when neuroplasticity is at its highest. Current mean age at diagnosis is 13 months in Denmark. Recent research has documented that an early-diagnosis set-up can lower diagnostic age in high-risk infants. The aim of the current study is to lower diagnostic age of CP regardless of neonatal risk factors. Additionally, we want to investigate if an early intervention program added to standard care is superior to standard care alone. METHODS: The current multicentre study CP-EDIT (Early Diagnosis and Intervention Trial) with the GO-PLAY intervention included (Goal Oriented ParentaL supported home ActivitY program), aims at testing the feasibility of an early diagnosis set-up and the GO-PLAY early intervention. CP-EDIT is a prospective cohort study, consecutively assessing approximately 500 infants at risk of CP. We will systematically collect data at inclusion (age 3-11 months) and follow a subset of participants (n = 300) with CP or at high risk of CP until the age of two years. The GO-PLAY early intervention will be tested in 80 infants with CP or high risk of CP. Focus is on eight areas related to implementation and perspectives of the families: early cerebral magnetic resonance imaging (MRI), early genetic testing, implementation of the General Movements Assessment method, analysis of the GO-PLAY early intervention, parental perspective of early intervention and early diagnosis, early prediction of CP, and comparative analysis of the Hand Assessment for Infants, Hammersmith Infant Neurological Examination, MRI, and the General Movements method. DISCUSSION: Early screening for CP is increasingly possible and an interim diagnosis of "high risk of CP" is recommended but not currently used in clinical care in Denmark. Additionally, there is a need to accelerate identification in mild or ambiguous cases to facilitate appropriate therapy early. Most studies on early diagnosis focus on identifying CP in infants below five months corrected age. Little is known about early diagnosis in the 50% of all CP cases that are discernible later in infancy. The current study aims at improving care of patients with CP even before they have an established diagnosis. TRIAL REGISTRATION: ClinicalTrials.gov ID 22013292 (reg. date 31/MAR/2023) for the CP-EDIT cohort and ID 22041835 (reg. date 31/MAR/2023) for the GO-PLAY trial.

OBJECTIVE: To compare the efficacy of an exercise and education programme with open-label placebo given as intra-articular injections of inert saline on pain and function in individuals with knee osteoarthritis (OA). METHODS: In this open-label, randomised controlled trial, we recruited adults aged ≥50 years with symptomatic and radiographically confirmed knee OA in Denmark. Participants were randomised 1:1 to undergo an 8-week exercise and education programme or four intra-articular saline injections over 8 weeks. Primary outcome was change from baseline to week 9 in the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire pain subscale (range 0 (worst)-100 (best)). Prespecified equivalence margins of ±8 KOOS pain points were chosen for the demonstration of comparable efficacy. Key secondary outcomes were the KOOS function and quality of life subscales, and patients' global assessment of disease impact. RESULTS: 206 adults were randomly assigned: 102 to exercise and education and 104 to intra-articular saline injections. For the primary outcome, the least squares mean changes in KOOS pain were 10.0 for exercise and education and 7.3 for saline injections (difference 2.7 points, 95% CI -0.6 to 6.0; test for equivalence p=0.0008). All group differences in the key secondary outcomes respected the predefined equivalence margins. Adverse events and serious adverse events were similar in the two groups. CONCLUSION: In individuals with knee OA, an 8-week exercise and education programme provided efficacy for symptomatic and functional improvements equivalent to that of four open-label intra-articular saline injections over 8 weeks. TRIAL REGISTRATION NUMBER: NCT03843931.

OBJECTIVE: To evaluate flare risk when tapering or withdrawing biologic or targeted synthetic DMARDs (bDMARDs or tsDMARDs) compared with continuation in patients with inflammatory arthritis in sustained remission or with low disease activity. METHODS: Articles were identified in the Cochrane Library, PubMed, Embase and Web of Science. Eligible trials were randomized controlled trials comparing tapering and/or withdrawal of bDMARDs and/or tsDMARDs with the standard dose in inflammatory arthritis. Random effects meta-analysis was performed with risk ratio (RR) or Peto's odds ratio (POR) for sparse events and 95% CI. RESULTS: The meta-analysis comprised 22 trials: 11 assessed tapering and 7 addressed withdrawal (4 assessed both). Only trials with an RA or axial SpA (axSpA) population were identified. An increased flare risk was demonstrated when b-/tsDMARD tapering was compared with continuation [RR 1.45 (95% CI 1.19, 1.77), I2 = 42.5%] and potentially increased for persistent flare [POR 1.56 (95% CI 0.97, 2.52), I2 = 0%]. Comparing TNF inhibitor (TNFi) withdrawal with continuation, a highly increased flare risk [RR 2.28 (95% CI 1.78, 2.93), I2 = 78%] and increased odds of persistent flare [POR 3.41 (95% CI 1.91, 6.09), I2 = 49%] were observed. No clear difference in flare risk between RA or axSpA was observed. CONCLUSION: A high risk for flare and persistent flare was demonstrated for TNFi withdrawal, whereas an increased risk for flare but not for persistent flare was observed for b-/tsDMARD tapering. Thus tapering seems to be the more favourable approach. REGISTRATION: PROSPERO (CRD42019136905).

BACKGROUND: Hyperoxia and oxidative stress may be associated with increased risk of myocardial injury. The authors hypothesized that a perioperative inspiratory oxygen fraction of 0.80 versus 0.30 would increase the degree of myocardial injury within the first 3 days of surgery, and that an antioxidant intervention would reduce degree of myocardial injury versus placebo. METHODS: A 2 × 2 factorial, randomized, blinded, multicenter trial enrolled patients older than 45 yr who had cardiovascular risk factors undergoing major noncardiac surgery. Factorial randomization allocated patients to one of two oxygen interventions from intubation and at 2 h after surgery, as well as antioxidant intervention or matching placebo. Antioxidants were 3 g IV vitamin C and 100 mg/kg N-acetylcysteine. The primary outcome was the degree of myocardial injury assessed by the area under the curve for high-sensitive troponin within the first 3 postoperative days. RESULTS: The authors randomized 600 participants from April 2018 to January 2020 and analyzed 576 patients for the primary outcome. Baseline and intraoperative characteristics did not differ between groups. The primary outcome was 35 ng · day/l (19 to 58) in the 80% oxygen group; 35 ng · day/l (17 to 56) in the 30% oxygen group; 35 ng · day/l (19 to 54) in the antioxidants group; and 33 ng · day/l (18 to 57) in the placebo group. The median difference between oxygen groups was 1.5 ng · day/l (95% CI, -2.5 to 5.3; P = 0.202) and -0.5 ng · day/l (95% CI, -4.5 to 3.0; P = 0.228) between antioxidant groups. Mortality at 30 days occurred in 9 of 576 patients (1.6%; odds ratio, 2.01 [95% CI, 0.50 to 8.1]; P = 0.329 for the 80% vs. 30% oxygen groups; and odds ratio, 0.79 [95% CI, 0.214 to 2.99]; P = 0.732 for the antioxidants vs. placebo groups). CONCLUSIONS: Perioperative interventions with high inspiratory oxygen fraction and antioxidants did not change the degree of myocardial injury within the first 3 days of surgery. This implies safety with 80% oxygen and no cardiovascular benefits of vitamin C and N-acetylcysteine in major noncardiac surgery.
